High impact if exploited, but EPSS currently rates exploitation as unlikely (1.13%). Schedule it in the normal patch cycle and watch for a rise in EPSS or a public exploit.
Description
FORT Validator versions prior to 1.5.2 will crash if an RPKI CA publishes an X.509 EE certificate. This will lead to RTR clients such as BGP routers to lose access to the RPKI VRP data set, effectively disabling Route Origin Validation.
